The leaf digestibility and mineral content of 10 grasses of Triticeae were analyzed by using scanning microscope and energy dispersive X ray technique.The order of leaf digestibility of the grasses was Elymus sibiricusHordeum brevisubulatumAgropyron cristatum cv.'Fairway'= E.CanadensisA.cristatum×A.desertorum cv.'Hycrest Mongnon' A.desertorum cv.'Nordan' E.excelsus≥Psathyrostachys juncea=E.dahuricusA.mongolicum. The mineral element content range in the leaves of the tested grasses was Mg 0.21%～0.57%,Si 0.90%～3.31%,P 0.27%～0.36%,S 0.36%～0.60%,Cl 0.21%～ 0.52% ,K 1.44%～3.06%,Ca 0.42%～0.98%,and the differences among the grasses were significant.
